how to disable the Hibernate and Suspend buttons in F13 ?

In the presence of long-lasting bugs such as: https://bugzilla.redhat.com/show_bug.cgi?id=556560 https://bugzilla.redhat.com/show_bug.cgi?id=612757 for some systems with some application loads it would be prudent to reduce the risk of memory corruption leading to file corruption (leading to re-install or restoration from backups) by disabling the Hibernate and Suspend buttons in e.g. Gnome. For older versions of Fedora, one can find clues for this in e.g.: http://faq.aslab.com/index.php?sid=43997&lang=en&action=artikel&a... These directions are not directly applicable to F13 (i.e. the checkboxen for can_hibernate and can_suspend no longer appear within the general group for apps, gnome-power-manager within gconf-editor. The most tempting nearby possibility within: Applications, System Tools, Configuration Editor is the apps, gnome-power-manager, buttons group. But changing most of these values to "nothing" changes neither the visibility of said command buttons nor changes the behavior when one is selected. I.e. Suspend or Hibernate will still cause filesystem corruption on some systems. Configuration Editor 2.30.0 Is there some other user-accessible configuration to prevent Suspend and Hibernate from being selected? How about for users of non-Gnome desktops? Bugzilla time?
